Application filed January 5, 19 05. Serial No. 239,808.

for its object to rovide an exceedingly Sim-- .ple, efficient, an durable device of this character especially ada ted for use in scrapin the spars of a vesse but may be employe for other scraping pur oses as well.

A further object of t vide a scraper-blade which can be readily screwed an unscrewed from the handle and which by reason of the cu -sha ed recess in said blade, hereinafter escri ed, enables said scraper-blade tobe firmly held against rotation while in use.

I With these and other objects in view the invention consists in the construction and novel arrangement of arts hereinafter described and shown, an particularly pointed out in the appended claim.

- invention.

In the drawings, forniin a part. of this specification, and in which e numerals of reference designate corresponding parts, Eigure 1 is a horizontalsectional view of a scraper conspirluctedin accordance with this scraper-blade. the scraper-blade.

' In Scrapers of this general type it is desirable as a matter .of convenience to arrange the blade and the handle at an obtuse angle, and this leads to difliculty in th'esecuring of the blade in position. In the present case the blade 1 is tapered in thickness from the head 2 to the scraping edge 3, and on themner face of theblade is an mtegr'al boss 4 of generall rectangular contour, as shown in Fig. 2, t 'e fac of the boss being at an acuteangle to the general at a right angle to t laneof the blade and fie longitudinal axis of the handle 9. In the. rear or inner face of the boss is formed a curved recess 5, and through said boss and the body of the blade e invention is to prog. is a 'face view of the i Fig. 3'is a sectional view ofextends a threaded opening 6. The threaded openin is ada ted to receive a screwthreaded s ank 7 ormed integral with a ferrule 8. Theferrule 8 is adapted to receive the handle 9*. The -;ferrule 8 is provided with a shoulder 9, which is rounded upon its outer surface and adapted to snugly fit and frictionally engage the cup-shaped recess 5, as clearly shown in Fi 1 of the drawings, by which the scraper-bla e is firmly held against rotation while being used in scraping.

The handle 9 is provided with a central bore or chamberlO, adapted to receive a file or suitable tool used for sharpening and dressing the scraper-blade 1. A coiled spring 12, having a cup-shaped receptacle 13, at-

tached to the outer end thereof, is located within the lower end of said bore or chamber to receive the end of said tool 11, the outer end of said bore or chamber 10 being closed by a screw-plug 14, as clearly shown in Fig. 1. The screw-plug 14- is providedwith a cup-shaped lower end. The cu shaped receptacle 13 and the cup-shaped ower end of the screw-plug 14 are adapted to hold the tool 11 firmly in its place, and thereby prevent said tool from rattling or making a noise when the scra er is in use.

It will be seen that my scraper-blade is very simple, efficient, and inexpensive and that said blade can be readily screwed and unscrewed from the handle and will be held firml against rotation.

W atI claim is.

A scraper including a blade and handle member arran ed at an obtuse angle with relation to eac other, the blade having on its inner face a; boss provided with a curved recess, there being a threaded opening exhandle member having a rounded shoulder fitting within the recess and a threaded shank fitting within said threaded opening in the blade,

In testimony whereof I have hereto affixed my signature in the presence of two witnesses. a
